A large asteroid of mass 71700 kg is at rest far away from any planets or stars. A much smaller asteroid, of mass 710 kg, is in a circular orbit about the first at a distance of 311 meters as a result of their mutual gravitational attraction. What is the speed of the second asteroid? Now suppose that the first and second asteroids carry charges of 3.68 C and -3.68 C, respectively. How fast would the second asteroid have to be moving in order to occupy the same circular orbit as before?
